Answer:

9) So basically we have what they all add up to and we have 2 of the sides out of 3 so what we can do is take the perimeter and minus the two sides we do know to get the one we dont know.

Set up:

10x+5y - (3x+4y) - (5x-y)

Remove parenthesees

10x+5y-3x-4y-5x+y

Simplify

2x+2y (ANSWER TO 9)

10) This one is giving us a triangle and we know all 3 sides. Its asking for that the perimeter is which is all of the sides added so we should add them.

Set up:

(3a+4) + (2a-7) + (5a^2 + a)

Group them together so we dont make mistakes

5a^2 + 3a+2a+a + 4-7

Simplify

5a^2 + 6a - 3 (ANSWER TO 10)

Answer:

9) 3rd side = 2x+2y

10) 5a^2 + 6a - 3

Step-by-step explanation:

9) 10x+5y - ( 3x+ 4y) = 7x + y

7x + y - ( 5x - y ) = 2x + 2y

Triangle QRS has vertices Q(-4,2),R(3,0), and S(4,3).
Dafna1 [17]

The coordinates of the vertices of \triangle Q'R'S' are Q'(x,y) = (0, -4), R'(x,y) = (7,-6) and S'(x,y) = (8, -3), respectively.

Vectorially speaking, a point is translated to another location on Cartesian plane by means of this expression:

A'(x,y) = A(x,y) + T(x,y) (1)

Where:

  • A(x,y) - Original point.
  • A'(x,y) - Translated point.
  • T(x,y) - Translation vector.

If we know that Q(x,y) = (-4,2), R(x,y) = (3,0), S(x,y) = (4, 3) and R'(x,y) = (7, -6)T(x,y) = (4, -6), then the coordinates of the vertices of the triangle Q'R'S' are:

Q'(x,y) = Q(x,y) + T(x,y)

Q'(x,y) = (-4,2) + (4,-6)

Q'(x,y) = (0, -4)

R'(x,y) = R(x,y) + T(x,y)

R'(x,y) = (3,0) +(4,-6)

R'(x,y) = (7,-6)

S'(x,y) = S(x,y) + T(x,y)

S'(x,y) = (4, 3) + (4, -6)

S'(x,y) = (8, -3)

The coordinates of the vertices of \triangle Q'R'S' are Q'(x,y) = (0, -4), R'(x,y) = (7,-6) and S'(x,y) = (8, -3), respectively.
